The eldest daughter of George II, Anne is the only English princess since the 15th century to rule alone in a foreign country. In the Netherlands, she is the least known of the women - from Amalia van Solms to Emma of Waldeck-Pyrmont - who have married into the House of Orange, but she is unique in holding real political power. This book uses hitherto unpublished private papers which provide a picture of 18th-century social life in London, Friesland and The Hague. But, more importantly, they show her influence on Dutch politics at a time of constitutional change, while letters to her father, her brother, Butcher Cumberland , and her cousin, Frederick the Great, show her playing a significant role on the European diplomatic stage.
